[PATCH v3 1/2] sequencer: move check_todo_list_from_file() to rebase-interactive.c

<20191202234759.26201-1-alban.gruin@gmail.com>

The message contained in `edit_todo_list_advice' (sequencer.c) is printed after the initial edit of the todo list if it can't be parsed or if commits were dropped. This is done either in complete_action() for `rebase -i', or in check_todo_list_from_file() for `rebase -p'.

Since we want to add this check when editing the list, we also want to use this message from edit_todo_list() (rebase-interactive.c). To this end, check_todo_list_from_file() is moved to rebase-interactive.c, and `edit_todo_list_advice' is copied there. In the next commit, complete_action() will stop using it, and `edit_todo_list_advice' will be removed from sequencer.c.
